PURPOSE:To attain the private line communication during the request assignment system (DAMA) communication service operation by registering number of private line communication lines and a slave station applying private line communication service in a master station. CONSTITUTION:When the master station registers a slave station applying private line communication and number of private communication lines, a relay line trunk 9a and the channel carrier of the slave station are reserved. When a line assignment request from an exchange 7 of the slave station is received by the master station, the channel carrier reserved for the private line communication is assigned. Moreover, when the relay line trunk in the idle state exists with respect to the line assignment request of the slave station other than the private line, the line assignment processing is applied. Thus, the DAMA communication and the private line communication are applied simultaneously. |
